The AT wiper seal featuring a Slipper Seal^® design consists of a PTFE slide ring for the wiper function and an elastomer O-ring as a preloading element. The AT wiper seal is characterized by low break-away and sliding friction and can therefore be used in low-lube conditions as well. Due to the material combination of the slide ring (PTFE) and the O-ring (elastomer), this product is suitable for a wide range of applications, especially for aggressive media and/or high temperatures. Several compounds can alternatively be selected according to the specific application profile.

Wiper rings serve to safeguard axially movable rods and pistons against ingress of dust, dirt, sand and swarf, thus protecting the guiding elements and seals and extending the service life of the sealing system.

• Excellent wear resistance.

• Minimal break-away and dynamic friction and no stick-slip tendency ensures uniform motion even at low speeds.

• Good energy efficiency due to low friction.

• High temperature resistance assured by suitable O-ring compound selection.

• Adaptable to nearly all media thanks to high chemical resistance of the sealing ring and large O-ring compound selection.

• Dimensions according to DIN ISO 6195, Type D.

• Installation in closed and undercut housings.

• Available in diameters from 4 to 3000 mm.

• Additional sizes of machined products available on short notice.

Range of application:

The material combination of the slipper ring (PTFE) and the O-ring (elastomer) makes this product suitable for a wide range of applications, especially for aggressive media and/or high temperatures. Multiple compounds can alternatively be selected according to the individual application profile.
